LIQUID-PROJECTNG DEVICE.

Application filed July 24, 1915. Serial No. 41,650.

" To all i071 om t man] concern:

Be it known that I, ALBERT V. SAMMIs, a citizen of the United States,and resident of Huntington, in the county of Suffolk and State of NewYork, have invented certain .ew and useful Improvements inLiquidrejecting Devices, of which the following a specification.

My invention relates to devices for eX-.

peiling and project-ing liquids contained in receptacles, andparticularly to devices by means of which the liquid .will be 'expelledfrom the vreceptacle, forcibly so as to be projected a considerabledistance, as may be ,fesirable in the casel of portable lire eX-tingnishers containing a lire-extinguishing liquid. rll`he purpose of myinvention is to provide a device of this character which will be simpleand effective in operation, and by means of which I am enabled to expeland vproject the liquid in aA practically ,con-

Iii

tinuous stream or jet.

rlhree embodiments of my invention are shown in the accompanyingdrawings in which- Figs. 1 and 2 are vertical sections, looking in thesame direction, and taken in the main through the center of thereceptacle, but showing most of the interior parts vin face view; Fig. 1differs from Fig. 2 by showing the upper intake tube broken off and in adifferent position, also by showing the handle in operating position,while Fig. 2 shows the handle folded down and in section; the airalve isomit-ted from Fig. 1, butis shown in section iii Fig. 2; the guides 57,58 appearing in Fig. 2 are omitted from Fig. 17 which sh ws the parts57, 58 in section, as well as the nozzle 25'; Fig. 3 is substantially acen-Y tral section of the. apparatus, taken at right angles to thedirection in which Fig..1 faces, and showing all the interior parts inface view, with' the exception of the guides 57, 58, which appear insection. Fig. a is a horizontal section taken on line 4 4 of A' 2; Fig.5 is a partial vert-ical'section through pump cylinder 2st.

In the said drawings, 2O indicates the cylindrical wall of a receptaclewhose ends are closed by heads 21 and 22. Through the head 21, at apoint as near its periphery as possible, extends, rigidly connectedtherevwith, a casing 23 to the lower portion of which is secured rigidlythe upper end of a rllhe lower end of said pump cylinderfis closed by aplug 25 (Fig. 5), whose main portion rests on theliead of thereceptacle, while a lateral extension projects through said head and isperforated to form a nozzle 25 through which the fluid vcontained in thereceptacle is expelled. The

upper .portion `of the'casing 23 receives another plug' 26 held againstlongitudinal movement by a shoulder on said casing and by an annularflange 27 on a cap 27, but is capable of turning around the axis of thepump cylinder. A vwasher 27 is interposed between the flange 27 portionof the plug 26 as well as the upper end ofthe casing 23, in order toinsure a tight joint. The casing 23 and cap 27 are secured to the head21 by screws 23', a washer 21 being preferably interposed between' thehead and the said cap. The head is formed with a boss 2l having fiatupper and the corresponding f plug 26.

and lower surfaces. Through an aXial hole in the plug 26 extends looselya piston rod 28 carrying at its lower end the piston 29 adapted toreciprocate in the pump cylinder. The upper Kend of the piston rod 28 isscrewed into, or otherwise rigidly secured to, a head 8O to which ispivotally connected, by a pin 32., the shank 32 of a handle 32 by meansof which Vthe pump is operated. A suitable packing held in place by agland insures a tight joint between the piston rod 28 and the plug 26.

rl`he plug 26 is formed with two segmental compartments 26, 26communicating with each other by channels '26* (Fig. Sa) which form` achamber `or passage with said compartments. Each of these segmentalcompartments Acfmtains arti-shaped valve (Fig. l2) capable of a slightlongitudinal*movement to cause its transverse central member to luncovera port 26am the lower portion of the plug 26, through whichlports thepassage 26', 26, 26* ray at times communicate with the chamber of thepump cylinder between the piston 29 and theplug 26. The vertical edgesof the parallel longitudinal en'd members of the valves 35 vare inguiding engagement with the inner wall ot the casing 23 and withvertical surfaces 26 on the inner portion of the plug Y26. Theselongitudinal members also limit the opening movement of the valve.vrBetween the segmental'compartments v26', 26 the plug 26 vis providedwith suitable recesses to receive scaling plugs S6 whichfmay be pressedoutward by springs 3,7, 37 (Fig, l1) or they maybe simply made ofelastic materialsuch as cork, Vin 'which case no separate springs arerequired (Fig. 8). These plugs 36,36 are adapted to close the ends oftubes38, 39 lead? ing to diamctrically opposite points ot the saidchamber of the plug 26. The saidtubes vextend to points near the bottomof the receptacle 20, the tube 3S, which acts as an outlet tubo,beingconnected withthe nozzle 25, while the tube'lf) conununicates withthe lower chamber of the pump cylinder at its bottom. The tube 39consists ot two parts between which is interposedza-valve casing 40containing a'checlr valve the transverse' central member v40 of whichcontrols the passage of the fluid by opening or closing the port oi' thevalve casing, while the longitudinal members 40, ofwhichthere are threein the particular construction shown, serve to guide the valve: in itsmovement toward and from its seat, and also to Vlimit the openingmovement of the valve.

From a point adjacent the lower end of the tube 39, another tube,v4l,loads from the lowermost portion of the'pump cylinderfto a pointslightly below thcvlower face of the rlhis tube V4l also consists of twoparts connected by a valve casing 42, which latter contains twochan'ibers 42, 42 communicating with each other by a passage 42f. Theends of this passage form ports adapted to be closed by the centraltransverse member 43 or 44 of suction valves adapted to become seated onsaid ports, said valves also having longitudinal members 43', 44respectively (four as shown) which not only guide the valve in itsopening or closing movement, but also limit the extent of its openingmovement. From the passage .42# a short tube 45 leads to a similarpassage 46* of a valve casing 46 having'two rchambers 46, 46 andcontaining two ballvalves 47, 47 with a guide rod 48 connecting them.The valve chambers 46, 46 communicate with tubes 49, respectively whichextend inv oppositeldirections fromY the casing 46 lengthwise ci thereceptacle, the free end of the tube 49 reachingtoa point adjacentthehead 2l of the receptacle, while thefree end of the tube 50reaches toapoint adjacent the other head 22 ofv the receptacle. The connectionbetweenA the tubes 49, 50 and the valve casing 46 is nota rigid one,Vbut loose and preferably universal, so as to allow the free ends ofthevtubes 49, 50 to assume a lower-most position adjacentto ythe heads ofthe receptacle. These tubes, which arerigid, have their attached endslextended into or through ball-shaped'members 49', 50 respectively,whichare held loosely within the valve chambers 46 and 46 by caps 5l, 52respectively, recessed to fit the said ballshaped members 49, 50. lnorder to prevent any longitudinal movement of theballshaped members 49',50 with their respective tubes 49, 50, andto insure a tight joint,perforateddislrs 53, v54 are providedwithin the valve chambers; thesedisks have recessed seats for the ball-shaped members andare pressedVagainst the vlatter by springs 55, 56 respectively. This will allow theball-shaped members a certain freedom of `movement around their centers,yet prevent any'leakage past their outer surfaces. The tubes 49, 50-arepreferably weighted at or near their tree ends, as shown at 49, 50 so asyto make sure that these tree ends or intakes, or at least one oi"them,-will always assumo a -position `lowermost in the'receptacle,irrespective of thevposition inwhich thereceptacle is being held andoperated. In order to insurethese swinging ends of the -tubes 49, 5()against getting calught and wedged between the other tubes within thereceptacle, lf provide guides 57, 58 (Figs. 2, 3 and 4) secured to thepump cylinder by flangesv 5?', 58. These guidesA are arranged in'suchaway that the'tubes 49, 50 willrslide on themto the lowest point in thereceptacle and cannot become caught in `other parts of the device. Thisof course applies only to cases wherethe receptacle is held andoperatedin sucha position' that the pump cylinder and connected tubes will belll) located below vthe remaining space ofthe receptacle.` In all otherpositions the free ends of the'tubest), 50, or at least one of them,will slide along the cylindrical wall 20 of the receptacle so as tobring the inlet of the active tube to the lowermost point of thereceptacle. l

In the exian'iple of my invention illustrated in the drawings, I haveshown the heads of the receptacle as being of spherical curvature, withthe centers of curvature lying in the axis yof the receptacle. rI`hisgives the receptacle `a. symmetrical shape and appearance. In this case,the points about which the intake tubes swing, that is the centers ofthe ball-sha eed members 49, 5i', will also lie in the axis of Ithe recptacle. However, the symmetrical arrangement is not essential to myinventiom'the above advantage being present as long as theheads of thereceptacle are spherically curved, with the centers of the curvaturecoinciding with the centers of the swinging movement of the respectiveintake tubes, so that the intake ends of the tubes 49, 50 will always beat the same distance from the heads of the receptacle (as near to themas practicable) lin whatever position the receptacle may be held.

rIhe head or top 2l of the receptacle is provided with a filling openingnormally closed by a cap 59, which, in the preferred form of myinvention, also contains an automatic air valve 59 ofv any approved construction, through wiiieh air will be drawn into the receptacle wheneverVliquid isr eX- pelled therefrom. The cap 59 is shown as a wing screwadapted to receive between its two wings the shank 32 of the foldinghanf dle 32, when the apparatus is not being used. The wings may beprovided with suitable holes so that the handle can be'tied to the wing'screw and'sealed thereto if desired. In order to bring the handle intothe operative position, it will be swung on its pivot, the pin 327,until its vshank is in alignment with the head 30. A sleeve 60surrounding the shank 32 a spring (il over the forked upper portion ofthe head 30 and will firmly lock the han-V dle to said head. After theapparatus Vhas been used, the sleeve 60 maybe pushed up against thetension of the spring 6l until it clears the upper edge of the head 30,and the handle can then be swung on its pivot until its shank rests onthe wing screw 59. l/Vhen folded as in Fig. 2, the handleisless exposedto injury say during shipment thanv when swung into the operatingposition (Figs. l and). *l i For the purpose of insuring vthe piston andthe head 30 against accidental longitup dinal movement, the followingllocking device is provided: rlthe head 30 has at its lower portion twosegmental ribs or flanges 30 located diametrically opposite each willthen be pushed down by Y other, each flange having at one end an outward`projection or stop 30, as Ashown in 'I Figs. 7, 9 and l0. Theseflanges, which are preferably slightly beveled on their upper faces atthe end opposite to the stop (Fig. 9) are adapted to be engaged fromabove by stationary segmental flanges 27 formed on the cap 27, onopposite sides thereof. In order to lock the head 30 againstlongitudinal movement, the handle 32 is pushed in fully to the positionshown in Figs. 7 and 9 and is then given a turn of about 900, takingwith it the head 30; that is, the handle will be turned until the stopsengage the edges 27 `on the flanges 27* (Figs. 10 and 17)'. The head 30with the piston rod andl piston will thus be securely locked againstlongitudinal movement. The slightly beveled ends of the flanges 30 willfacilitate l the entrance of said flanges between the flanges 27 t andthe flanges 27. A felt washer 3l is interposed between the lower face ofthe head 30 and the upper face of the plug 26, so that in thel lockedposition the head 30 will be pressed against the flanges 27 f. If it*isy desired to unlock the head 30, the handle 32 will be turned back tothe position Figs. 7 and 9, the'l stops 39 preventing the head 30 lfrombeing turned too far. The flanges 30'; will then' have cleared theflanges 27* completely, and 'tte pump can be operated readilyv (Figs. G,7 and 9).

The following device is employed to causev the plug 26 to turn with thehead 30 when the latter is in its lowermost position. The valve casing26 is provided at diametrically opposite points with projections orflanges 26c extending upwardly between the head 30 and the cap 27 (seeFigs. 6 and 7) and of such a circumferential extent as to lit be tweenthe Aflanges 30. Those portions of the radial edges of the flange 30which are adapted to be engaged by the projections 26C, form seats forsaid projections to permit longitudinal separation of the handle fromthe plug while compelling them 'to turnv in unison when said projectionsare engaged by their seats. Those portions of the flanges 30 which fitunder the flanges'2'7f constitute the means for locking the handleagainst longitudinal movement. Byfturninp;

sage 26', 26, 26:. .lhile I 'have shown in the drawings two plugs 36,3.6', I desire it to be understood that the action ofthe plug`sealingthe tubev 39 is not material` and that se p vi--I it `would *besuliicient `to 'provide a single plug having -for its office the sealingoit the tube 33. l prefer however to employ two plugs for the followingreason "it only'one plug is used, care will have to be Aexercised inassembling the apparatus to have this plug -in the position of 4the plug36 Vin Fig. 8, since if the plug were by Amistake placed in the positionof the plug 36 in Fig. '8, the outlet tube 38 would remain 'unseale'dafter the turning ot the head 30 Vinto the position shown vin Fig.l 11.W hen Vhowever two plugs are used, it ldoesnot kmatter how the parts areplaced in assembling, since'one or the other of the plugswill be sure tocome into the position'sealing the tube 38.

The location ofthe pump and 'its operating :handle to one side 4of thereceptacle offers Athe advantage oit affording a Vrelatively largeunobstructed chamber iin lwhich the intake tubes 49,50 'may swing (seeFigs. 3 and 4). Furthermore, this arrangement enables ine to 4locate thepoints Yabout whieh the intake 'tubes swing, in the :longitudinalcentral axis of the receptacle. The ,device for lockingthe handleagainst longitudinal movement is so arranged that in the locked position(Fig. :10) thehandlelproper 32 will extend transversely, as shown inFig. 16 (that is to say, the yhandle proper will be perpendicularto aplane containing the axes of the receptacle and ott `the pump). Thehandle proper will therefore in the locked position-stand so-asito ymakeit easyto suspend the device against ya wall saybyfmeans of adouble hookengaging theundersurtace of the handle proper Lateah side'ottheshank'32. li/Vhein'asshown in Fig. 16,the endsl of the handle "properiinthe -saidlocked position project beyond fthe'outline of the receptacle,l secure the further Aadvantage of preventing or hindering 4the rollingdi' the receptacle it kept Ain a horizontal position in a tool box orthe'like.

nstead ot combining Vthe'automatic air inlet with 'the flling 'capfniayladmt the air to the'interiorotthereceptacle through thc 'handleAand piston rod, as "has Ibeen .shown in Fig. 17. Forthispurposethepiston rod, which in this case must behollow,

communicates with'the outside air through the'head 30'andhasat'its'upp'er end an internal screw thread lG3 adapted to receivea valveseat 64 with-a springspressed valve 65 opening toward the interior ofthe ,piston rod. `The lower portion of thepiston'rod is likewisescrewethreaded internallyzto receive a suitable packing G6 surroundingstationary tube 67,the ylower -end ot Awhich is secured to Vthe plug 25and communicates with the inner space of the Treceptacle through aVchannel 25* in said plug. The plug25lis exactly the samelas the'plug 25shown in the main form of my invention, except torthe provisiono-tthechannel 25?.

The.valve 47, 47 acting bygravity, .the liquid 'will always be sucked inthrough 'that one ofthe tubes 50 whose intake is at the lowest level,while the communication of the other tube tothe channel is :closed bythecorresponding valve member 4T `or 47,.so that theV air in the upper partot' .thefreceptacle can never be sucked into the .pump cylinder. otth'eapparatus being held perfeetly horizontal, both intake tubes 49, 50 willbe open at't-he same time to the passage 464i, so that liquid `will bedrawn into the ,pump .from 'both tubes, thetfree ends otwhich of courserare both within 'the liquid in such case. 'The valve 43, 43 or 44, 44of course will be open in the direction 'from whichithe suekingractionis exerted, .and simultaneously therewith,'thevpressure created in thechamberabove the lpiston also tends to keep the -other 'valve 44, 44',or 43, 43 respectively, closed. `When the piston has reached itsuppermost position and the space below it thasvbeenentirely filledwit-hiliquid, the return stroke of the piston will i'orce this liquidout :through the tube 39, valve 40 (which will be in theopenposition-owing to the ,pressure vexerted from below), finto'"thecompartment 26 formed in the plug` :26. As has" been vdescribedabove, V'the un- 5locking-oithe handle.has'brought the l plugs 36, 36which in-the positionotrest, with theh-andle locked, sealthepentlsofthe-tubes 38 and 39, Vintothe `position shown zintFig..

S, -so that'thesetubes Vvrein Communication :with cach other v:throughpassage 26', 2G, 2G*l The'liquidwill lthen be forced from through thepassages 25. At the same@timeliquidwillbe sucked into the upper-chamberofthe pump cylinder through one of 'the intake Vtubes 49 'or 50,'thevalve casing 46,tube"45,valve casing v,42v andl tube `4l, 'thevalve'member w44 duringthis stroke being'pressed on its-seat owing tothe ypressure created in the lower partfot fthe cylinder, so: that theliquid =will pass from thetube45 and 'chann'el 142* Ipast'the jvalvemember 44:"to vthe chamber 42 ol? the valve casing 42.

At the next outward stroke ot thelpistonq the liquid which now'fills-the chamber ot In the unlikely event -llll Ll l) the cylinder'between the piston 29 and the plugh 26, will be forced into the passage26, 26 26* through the openings 26, by lifting the ll-shaped valvemembers j. Owing to the pressure thus created in the passage 26, 26,26a: the check valve 40 located in the tube 39 will be closed, so thatthe liquid will be forced through the tube 38 and ejected through thenozzle 25. During this outward stroke of the pump piston, the lowerchamber of the pump cylinder will again be lled as described above, andthe operation can be repeated Vas often as desired, or as long as thereis any liquid contained in the receptacle. During the inward stroke otthe piston, thevalve members 35 will be pressed down on their seats, soas to close the openings 26a and to prevent any liquid passing throughthe passage 26, Q6 26* from being sucked into the chamber of t-he pumpcylinder between the plug 26 and the piston 29. As the liquid isexpelled at each stroke, a corresponding volume of air will of coursebe' drawn in through the automatic valve 59 or 65.

In some cases it may be desirable to place the pump andconnect-ingvparts out-- side of the receptacle. This form of myinvention has been illustrated in Figs. 18 and 19. All parts can readilybe placed outside the receptacle, except the intake tubes 49, and thevalve casing 46 connecting them. These are of course arranged within thereceptacle in the same way as described above in connection with themain torni ot my invention." The tube connecting the valve casing 46with the valve casing 42 in this case extends through the wall otthereceptacle and consists preferably ot two parts 45', 45 connected by a.union 45:22 All other part-s are the same as in the other form and arepreferably proterted by a tube 68 surrounding them,` this tube beingsecured to the receptacle by suitable clampingrings 69. The operation ofthis form of my invention is exactly the same as described above withregard to the main form.

The operation of my improved liquidprojecting device is very simple,while at the same time it .is very effective. By a succession ot quickin-and-out strokes I obtain a practically continuous stream ot liquidissuing :lrom the nozzle of theV receptacle.' The receptacle may be heldand the pump operated in any desired position. The intake tubes arearranged in such a manner that the free end of at least one of them willpractically always be immerse-d in the liquid.

lVhile my device has been described in connection with a fireextinguisher and is primarily intended for such use, it may be adaptedtor other uses, such as for instance vthe receptacle to withdraw liquid,thereftrom, aid .pump being provided with an outlet to discharge suchliquid, a piston ar-` ranged to reciprocate, in said cylinder, a handletor operating said piston, said handle being capable oit turningrelatively tothe cylinder, a plug which is normally stationary anddisconnected from the handle, said plug being arranged adjacent to saidoutlet and capable of turning relatively to the cylinder about the sameaxis as saidhandle, a valve carried by said plug and controlling saidoutlet, and means for connecting said handle and plug so that they willturn in unison about the same axis.`
